    or one of the programs... here

    Or perhaps even download the Sight Reduction Tables table from the site and print (I recommend the larger one for accuracy) then use that to reduce the sights.
    they are more or less Ageton tables giving logarithms for sine and cosine between 0° 0.0' and 180°, it is given in 0.2' steps in the larger table the smaller one is every 1'.

    I attached a workform that I have slightly modified, basically just added a quick reference for Sha, GHA, Lha... (image) and a box for lat, lon date time.
    anyone spotting anything wrong please notify me ASAP I have not used this version yet but intend to this summer.
    the reference image of the angles I added as Wife and her friend keep mixing them up...
